How many liters are there in 3.49 x 10^22 molecules of O2 at STP

I think 767.8

Explanation:

I first did 10 times 22 bc that little carrot sign means squared so I did 10 times 22 and that equaled 220, then I did 3.49 times 220 and that is the answer which is 767.8

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
